Word n°3: scalable!

How do you translate “scalable” into French? As in scalable solutions or scalable software?

Scalable solutions: à echelle variable meaning the solution can be adapted to the size of the company/business concern.

Scalable software: logiciel évolutif, meaning a programme (no, you can’t say “a software” since software, like advice, furniture, news, information and toast is uncountable) that can be resized (mostly upward) to meet new needs.
